The SGI-8 Tachometer Interface Unit is designed to allow a factory tachometer to function accurately after performing an engine swap to an engine with a different number of cylinders or tach signal. If you are swapping out a V-6 for a V-8 and you need to recalibrate the tach signal from the V-8 to make it read accurately on the factory V-6 tachometer, the SGI-8 will do the job. The SGI-8 is capable of recalibrating tachometer signals for nearly any engine swap combination.

Unit measures 4" x 3" x 1" and is designed to be mounted inside a vehicle.
